  • Wall Blowers Optimization in Boilers
    There are many methods used for optimization of wall blower operation in boiler furnace, like the manual method, heat flux measurement method, and the automated method. The manual method is discussed as this will bring out the philosophy involved in optimizing wall blower operation.
  • Reciprocating Gas Engines for Biomass Powerplants
    Gas engines are a more economical and environmentally friendly choice for low output power, generation using gaseous fuels. This article describes the functioning of gas engines and looks at how they score over gas turbines in the low output range.
  • Bank Tube Failures in Bi-drum Boilers
    Bank tubes in bi-drum boilers act as raisers and down comers between the two drums. They also carry the load of the bottom drum and its down comer. Failure in these tubes needs to be attended depending upon the type of failure and the location of failure.
  • Electric Power Generators: How They Work
    Electricity powers your light switches, computers, phones and more! How do we generate all the electricity used to power are homes? Learn how Electric Power Generators work here.
  • Cleaning High Pressure Boiler Internal Surfaces
    High pressure boilers need very clean internal surfaces. The pre-commissioning cleaning involves Alkali boil out to remove any oily materials, Acid Cleaning to clean up mill scales and Steam blowing to clean superheaters, reheater, and piping. Post-commissioning cleaning is specific to each boiler.
  • P91 - The Workhorse of the Power Industry
    For the last two decades the power industry standard material for high temperature applications is the P91 or T91 grade material. What is this material? What are its benefits? What are the precautions to be taken during construction?
  • Using Coal Petrography for Combustion Problem Solving
    Petrographic analysis can give useful information about the combustion of pulverized coal. Petrographic analysis of coal has been used to evaluate the efficiency of a pulverized coal fired boiler since 1968.
  • Uranium 235 Vs. Thorium 90 Compared - Nuclear Power Generation Perspective
    Uranium – 235 is currently used as fuel in the world’s nuclear reactors, producing High Level Wastes such as Plutonium-238 (half life 87 yrs). However, when irradiated Thorium-232 is used as a fuel, it is projected to produce up to 10,000 times less long-lived radioactive waste than uranium-235.
  • Mini Nuclear Power Plants
    Mini nuclear power plants are expected to be in service in the next few years. They have many advantages over large nuclear plants.
  • How to Conduct a Boiler Performance Test
    The performance test in a boiler evaluates the practically achievable boiler efficiency. Performance tests are also carried out to prove boiler guarantees. As guarantees involve contractual conditions, the procedure involved are more elaborate than the test for evaluating performance.
